You should ask any future questions on the program itself instead of here, this is not the place for that kind of question.

You need to define mouseClicked yourself as a function. It runs whenever you click the mouse in the program.

I can't ask questions on the actual program itself, that is why I posted here instead. Could you elaborate on that second point for me?

mouseClicked is a function, like drawStars. I think that the "drawStars();" is supposed to be within the mouseClicked function. This is what the end of my solution looked like:

By the way, if you are doing a Challenge, you can save the program separately (such as by copying the code, opening a new program, pasting in the code, then saving the new program) and make a Help Request from the program.

Thank you, worked like a charm!
